# Linux Shell Control Commands
|
|
|
|
Turning the display on or off is possible directly in a Linux shell!
|
|
|
|
Add your user to the `dialout` group for access to `/dev/ttyACM0`:
|
|
|
|
```shell
|
|
sudo usermod -a -G dialout $USER
|
|
```
|
|
|
|
> You may have to log out and back in for group changes to take effect.
|
|
> If not using a Debian based Linux, the tty device might have a different name, or not using the `dialout` group.
|
|
|
|
|
|
## Turn display on
|
|
|
|
```shell
|
|
stty -F /dev/ttyACM0 raw
|
|
printf "\252U\252U\v\0\0\0" > /dev/ttyACM0
|
|
```
|
|
|
|
## Turn display off
|
|
|
|
```shell
|
|
stty -F /dev/ttyACM0 raw
|
|
printf "\252U\252U\12\0\0\0" > /dev/ttyACM0
|
|
```
